Introduction
Use the procedures in this document to power off or reboot your PowerStore appliances, nodes, or cluster gracefully. As part
of a robust disaster recovery plan, it is recommended that you print and follow this procedure to test the planned shutdown and
restart procedures.
Topics:
• Power control procedure considerations
• Power control procedures preview
Power control procedure considerations
Note the following before you get started:
● Powering off a node, appliance, or cluster can take several minutes to complete.
● In a true emergency power off situation, turn the cabinet power switches to the off position to immediately remove power
from the all cabinet components.
● Working with hardware may cause electrostatic discharge that could damage your hardware. Before working with any
hardware, take precautions around handling replaceable units. See Safety precautions for handling replaceable units on page
19.
● If you are relocating or replacing hardware, to help identify associated enclosures when you are ready to cable and power on:
○ Ensure that you make a note of the cabling between enclosures and the appliances. If you used cable labels at the time of
initial installation, reconnecting the cables is easier.
○ Ensure that you also record the Dell service tag numbers of all enclosures in your cluster.
● A PowerStore X model appliance consists of two ESXi host nodes (node A and node B), running VMware ESXi version 6.7,
and a controller VM on each that runs the PowerStore operating environment. Powering off a PowerStore X model node or
cluster requires operations in the associated VMware vCenter server. See the VMware documentation for more information
about the vCenter server commands.
● Nodes in the appliance power on into the same mode they were in before the appliance was powered off. If a node powers
on in service mode:
1. Log in to the appliance from an SSH client.
2. Run the svc_rescue_state clear command to clear the boot mode.
3. Run the svc_node reboot command.
○ For a PowerStore T model node, this command reboots the node itself.
○ For a PowerStore X model node, only the PowerStore controller VM gets rebooted.
Once rebooted, the node returns to normal mode.
NOTE:
The svc_node service script, with reboot and shutdown arguments, is typically used in the context of
rebooting or powering off a PowerStore T model node.
Use the VMware vCenter server commands to reboot or power off a PowerStore X model node. In PowerStore
X model nodes, running the svc_node service script with reboot or shutdown arguments only affects the
PowerStore controller VM.
Unless specifically directed by your service provider, for PowerStore X model appliances, use the svc_node service
script only for the following purposes:
○ Go out of service mode (reboot argument).
○ Power on the node (power_on argument).
For more information about the service scripts, see the PowerStore Service Scripts Guide.
● If both nodes in an appliance reboot in service mode, always return Node A to normal mode first to avoid management
software conflicts. After Node A is operating normally, you can return Node B to normal mode.

Safety precautions for handling replaceable
units
Review these safety considerations before replacing any parts to avoid damage to your system.
Topics:
• Handling replaceable units
Handling replaceable units
This section describes the precautions that you must take and the general procedures that you must follow when removing,
installing, and storing any replaceable unit.
Avoiding electrostatic discharge (ESD) damage
When replacing or installing hardware units, you can inadvertently damage the sensitive electronic circuits in the equipment by
simply touching them.
Electrostatic charge that has accumulated on your body discharges through the circuits. If the air in the work area is very dry,
run a humidifier in the work area to help decrease the risk of ESD damage.
Follow these procedures to prevent equipment damage:
● Provide enough room to work on the equipment.
● Clear the work site of any unnecessary materials or materials that naturally build up electrostatic charge, such as foam
packaging, foam cups, cellophane wrappers, and similar items.
● Do not remove replacement or upgrade units from their antistatic packaging until you are ready to install them.
● Before you begin service, gather together the ESD kit and all other materials you need.
● Once servicing begins, avoid moving away from the work site; otherwise, you may build up an electrostatic charge.
● Use ESD anti-static gloves or an ESD wristband (with strap).
If using an ESD wristband with a strap:
○ Attach the clip of the ESD wristband to the ESD bracket or bare metal on a cabinet/rack or enclosure.
○ Wrap the ESD wristband around your wrist with the metal button against your skin.
○ If a tester is available, test the wristband.
● If an emergency arises and the ESD kit is not available, follow the procedures in Emergency Procedures (without an ESD kit).
Emergency procedures (without an electrostatic discharge kit)
In an emergency when an electrostatic discharge (ESD) kit is not available, use the following precautions to reduce the
possibility of an electrostatic discharge by ensuring that your body and the subassembly are at the same electrostatic potential.
NOTE: These precautions are not a substitute for the use of an ESD kit. Follow them only in the event of an emergency.
● Before touching any unit, touch a bare (unpainted) metal surface of the cabinet/rack or enclosure.
● Before removing any unit from its antistatic bag, place one hand firmly on a bare metal surface of the cabinet/rack or
enclosure, and at the same time, pick up the unit while it is still sealed in the antistatic bag. At the same time, do not move
around the room or touch other furnishings, personnel, or surfaces until you have installed the unit.
● When you remove a unit from the antistatic bag, avoid touching any electronic components and circuits on it.
● If you must move around the room or touch other surfaces before installing a unit, first place the unit back in the antistatic
bag. When you are ready again to install the unit, repeat these procedures.

Hardware acclimation times
Units must acclimate to the operating environment before applying power. This requires the unpackaged system or component
to reside in the operating environment for up to 16 hours in order to thermally stabilize and prevent condensation.

Unknown <86°F (30°C) 16 hours
● If there are signs of condensation after the recommended acclimation time has passed, allow an additional 8 hours to
stabilize.
● Systems and components must not experience changes in temperature and humidity that are likely to cause condensation
to form on or in that system or component. Do not exceed the shipping and storage temperature gradient of 45°F/hr
(25°C/hr).
Removing, installing, or storing replaceable units
Use the following precautions when removing, handling, or storing replaceable units:
CAUTION:
Some replaceable units have the majority of their weight in the rear of the component. Ensure that
the back end of the replaceable unit is supported while installing or removing it. Dropping a replaceable unit
could result in personal injury or damage to the equipment.
NOTE: For a module that must be installed into a slot in an enclosure, examine the rear connectors on the module for any
damage before attempting its installation.
CAUTION: A sudden jar, drop, or even a moderate vibration can permanently damage some sensitive replaceable
units.
● Do not remove a faulted replaceable unit until you have the replacement available.
● When handling replaceable units, avoid electrostatic discharge (ESD) by wearing ESD anti-static gloves or an ESD wristband
with a strap. For additional information, refer to Avoiding electrostatic discharge (ESD) damage on page 19.
● Avoid touching any exposed electronic components and circuits on the replaceable unit.
● Never use excessive force to remove or install a replaceable unit. Take time to read the instructions carefully.
● Store a replaceable unit in the antistatic bag and the specially designed shipping container in which you received it. Use the
antistatic bag and special shipping container when you need to return the replaceable unit.
● Replaceable units must acclimate to the operating environment before applying power. This requires the unpackaged
component to reside in the operating environment for up to 16 hours in order to thermally stabilize and prevent
